DC voltage current meter 100v 10A wiring

How to wire Chinese 100v/10A voltage and ammeter. When you are buying a DC voltage and current meter. you don’t get sufficient information about the connection of the digital meter. Insufficient information will cause complications or doubts about connections.

so, I decided to share the exact circuit diagrams to clear the doubts. First, we need to know how it’s working. The display works with the DC voltage source. don’t try to give the direct AC power supply. The direct power supply from the AC source will be dangerous to you, and it may explode. so be knowledgeable about the input voltage supply.

The display consists of a seven-segment display and an electronics board to sense the voltage and ampere. The device consists of 5 wires. It makes you confused.

  • The narrow red and black wire. The red wire is the input voltage for working the display and the black is the negative wire.
  • Next gauged red and black wire. It is not the input power supply, it is for sensing the ampere of the output supply. The black wire is connected to the input negative voltage and the red wire is negative for the output supply. ( don’t misunderstand the color of the wire ).
